The plate 30 has Fig. 1 is a front view in elevation of a heater a downturned end iiange 38 which is bolted to a 5 to which the' invention has been applied; plate 39 and through this plate 39 to a cup shaped 35 Fig. 2 is a sectional view taken on the line 2 2 housing 40 which 1s prcvided with spacing blocks of Fig. 1; 4I and 42 and mounting blocks 43 and 44 to po- Fig. 3 is a sectional view taken on the line 3 3 sition the headers I4 and I1 in the housing 40. of Fig. 2; and The plate 39 has an aperture 45 in which the fan D Fig. 4 is a sectional view taken on the line 4-4 22 operates, this aperture beine hanged. as indi- 40 of Fig. 2. cated at 46, inwardly toward the radiating unit. Referring now to the drawings, the invention The plate 39 has a portion 41 Which extends at is shown as embodied in a heating apparatus of right angles to the portion covering the cup indicated at I3 so that it may be clamped on a covers the horizontal heat radiating unit and 50 dash board by a suitable nut. not shown, to abuts the cup shaped housing 40 t0 Complete the mount the heating device in position. The inlet enclosure ci the device.

I6 mounted positioning the header 20. It also has mount- 55 ing blocks BS and 5l to which the horizontal portion 41 is secured by means of suitable screws such as and B8. Blocks 53 and M are duplicated at the back end of the housing 50, and the housing is secured by means of these blocks to a horizontal flange 51 provided at the lower end of the plate 29 by means of screws 58.

The housing l0 has a front aperture which is covered by a plurality of shutters 58, B0, and 8|. These shutters are supported by a pair of frame members 82 and 83, the shutters being provided with suitable ears 64 and 85 which are secured by rivets and 81 to the frame members 62 and 83. Each shutter is provided with a finger piece 68 by means of which it may be opened by the hand. The housing 60 is provided with an aperture 88 facing downwardly, and, at the front and rear ends of the aperture, the housing is provided with downturned anges 1li-and 1i to which a plurality of shutters 12 are hinged, the shutters being provided with suitable flanges 13 riveted by means of rivets 14 to the flanges 10 and 1|.

The shutters 59, 80, and Bl are individually operable, but the shutters 12 are somewhat inaccessible, being placed on the bottom of the heating unit. Means are provided whereby these shutters may be a hand lever 15 which is located at the iront of the housing 40. For this purpose, the three shutters 12 are linked together by a link 18- at their free ends, this link being pivoted asshown to suitable ears 11 provided on the shutters 12. 0n the central one of the shutters 12 at the end opposite the link 16, a pinion 18 is fixed, for example by soldering or welding it, to a flange 19 on the shutter, and this pinion meshes with a small gear that is carried on a shaft 8l that is journalled in an enlarged portion 82 on the bottom of the housing 40. The hand lever 15 has a hub 83 secured by a set screw 84 to th shaft 8i.

The header chamber l-1 is recessed as shown at l5 to provide space for It is evident that, by

the gear 80. turning the hand lever 15, the gear l0 may be rotated to in turn actuate operated in unison by turningA the pinion 1I for opening and closing the shutters 12.

The operation of the device, it is believed. will be readily understood. Two heat radiating sections are provided at right angles to each other, and air can be forced through either or both of them at a rate controllable by setting the shutters associated therewith. In this fashion, the heating apparatus may be adjusted to give the desired direction to the heated air from the heat radiating units. Arranging the units in this fashion, gives a large radiating surface and a long path of circulation for the heating fluid making for a more rapid transfer of heat from the fluid to the air in the car.

While certain embodiments of the invention have been shown and described, it is to be understool that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims in which it is the intention to claim all novelty inherent in the invention as broadly as possible in view of the prior art.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is:

l. Heating apparatus of the character described comprising, in combination: a casing; a vertical and a horizontal radiator housed in said casing in L-relationship; a common header at the apex of the angle between the radiators acting as outlet for one of said radiators and inlet for the remaining radiator; inlet and outlet headers for the respective radiators at the free ends thereof; a motor in said casing; and a pair of fans one facing each of said radiators; one of said fans directly driven by the armature shaft of said motor and the other thereof driven by gears from said shaft.

2. The combination of claim 1 with shutters in said casing in front of the respective radiators and with remote control for the shutters facing n
